R1 Concepts 623-47089R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-47089R is a precision-engineered drilled disc brake rotor from R1 Concepts' RNC (eLINE Black) Series, designed as a direct-fit replacement that delivers enhanced stopping power over stock rotors. Precision-machined to OEM mounting specifications, this rotor installs without modification for a straightforward upgrade.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk to maximize heat dissipation, reduce brake fade, and help prevent rotor cracking under thermal stress
• Advanced Black Coating: Protective anti-corrosion coating guards non-contact surfaces against rust and environmental wear, maintaining appearance and extending rotor life
• Direct-Fit Replacement: Machined to OEM dimensions for bolt-on installation with no modifications required
• Improved Wet-Weather Performance: Drilled pattern channels away water and debris, reducing pad glazing and improving bite in wet conditions
• Premium G3000 Cast Iron Construction: High-grade cast iron rotor material delivers consistent thermal performance and long service life
• Right-Side (Passenger Side) Rotor: Designated by the "R" suffix in the part number — sold individually

The R1 Concepts RNC Series drilled brake rotor is an ideal upgrade for drivers seeking improved braking performance and a more aggressive appearance. Always replace brake pads when installing new rotors and follow proper bed-in procedures to ensure optimal performance and even wear.
